Default 149 engine teardown for cam replacement

Thanks for all the advise on my other thread about the broken cam shaft. Thanks to all that responded. It created a lot of interest and a lot of great information was given. At the end of the thread, I was having trouble with starting the engine. It would only start when the ign. switch went from start to the run position. I can't remember if That issue was resolved or not. That is how bad my memory is.
This week I decided that I could take the engine apart and replace the cam shaft. Today, the only thing left in the block is the governor gear and what ever is associated with it. The engine came apart remarkably well. Had a problem with the rear balance gear. It was hanging at the top of the shaft. Could not see or feel any thing at the top to keep it from coming off. Pried it off with a large screwdriver and it came off. The bottom of the cylinder has a small piece missing. (first picture) Something has happened to this engine prior to my owning it. Probably why it has a .010 bore and new piston. I will not put the balance gears back in engine. Top ring has .010 end ring gap. Second ring has a .035 end gap. I would like to have new valve seats and valve guides installed, but so far I have been unable to find a shop willing to do this. One of the members may have a used cam shaft to sell to me.
I believe this engine will be ok to put back together with new rings and a used cam shaft and new crank seals. Going to attach pictures because everyone likes pictures. Thanks for reading this, enjoy the pictures and have a great day.
Bob
